If you look close at the last keyboard that you posted, it looks like you have one keyboard on top of another???

it's because the keys are placed different on the French AZERTY keyboard compared to the English QWERTY keyboard... the only way to fix this is to make a new one based on that layout OR make a plist only Keyboard that's universally compatible with all language layouts...

Yes i can change my layout to qwerty, but it's more simple , for me, with azertyui

All the images are there for the azerty keyboard. Do they just need to be called correctly? i am not the expert on ColorKeyboard, but I believe everything is there to make it work correctly, it seems like it just needs to call the right image file.

I may be way wrong here, but look at image #27 that should work for the azerty keyboard.
